BS!
Complete and utter BS!
Apple won't be using OLED displays ever.
Ming Chi Kuo trolled the media saying the next iPhone will have OLED (buzz), and now he's making up excuses (kill).
If Apple were to put an OLED in 2017, they would have decided about it in 2013, and primed the suppliers in 2014, tested in 2015, manufactured in 2016 to release in 2017. What do people think Apple is? A bunch of amateurs that decide their products roadmap 2 weeks before releasing them?
But I'm waiting for that guy that will say the next iPhone will suck because it doesn't have an headphone jack.
